This IDC study is a translation of the Japanese document IDC #JPJ42855918. It presents quantitative and qualitative analyses on the Japan private cloud market based on information compiled until early September 2018. Growth in the Japan private cloud market today is driven by the migration from traditional IT. The increased in DX-related utilization will be a vital growth accelerator for this market in the future. Today, vendors' power relationship and ecosystems in the Japan market are shifting rapidly as hybrid cloud grows more important and competes with public cloud and private cloud. "Vendors must enhance their operations management flexibility, encourage cloud-native architecture, and step up their approach for developers," says Satoshi Matsumoto, IT services research director, IDC Japan.
